Enhance vehicle stability and ride quality with adjustable air springs.

The Firestone Coil-Rite Air Helper Spring Kit is designed to improve the ride, handling, and braking of various vehicles including cars, minivans, vans, light trucks, RVs, and SUVs. These air helper springs fit inside existing coil spring suspensions, providing additional support and creating a variable rate spring that adjusts to varying loads and road conditions. Made from durable polyurethane, the Coil-Rite springs are engineered to withstand the rigors of coil-sprung suspensions while offering a smooth ride and enhanced vehicle stability.

With a leveling capacity of 500 to 1000 pounds, the adjustable air pressure range of 5 to 35 PSI allows for easy customization based on load requirements. This feature not only improves steering control and braking effectiveness but also helps maintain level headlight beams and reduces tire wear. The protective air cushion minimizes the risk of bottoming out by softening the contact between the axle and frame, ensuring a more comfortable driving experience.

Installation is straightforward, requiring no drilling, and includes all necessary components such as brackets, air springs, hardware, and air line for a quick setup. The Firestone Coil-Rite Air Helper Spring Kit is an effective solution for those seeking to enhance their vehicle's performance under heavy loading and adverse conditions.
